The Redding 204 Ruger Full Length Die Set (Model 80287) is a precision 2-die reloading system engineered to return fired .204 Ruger brass to minimum SAAMI factory dimensions and seat projectiles concentrically. Machined from heat-treated alloy steel on precision lathes, this mechanical tooling set operates on standard reloading presses utilising an industry-standard 7/8"-14 thread pitch. The full-length sizing die decaps, bumps the shoulder back, and sizes the entire case body in a single pass to ensure dependable feeding and extraction across bolt-action and semi-automatic platforms, while the seating die features an internal bullet guide and a built-in roll-crimp ring.

Key Features

• Full-Length Resizing: Features an integrated decapping rod assembly and steel expander button to resize the full case body and expand the neck in one pass.
• Precise Projectile Alignment: The seating die utilizes an internal bullet guide to align .204-calibre projectiles straight into the case neck, incorporating a built-in roll-crimp ring.
• Modular Compatibility: Supports optional Redding enhancements, including the Carbide Size Button Kit (#RE37203) and Bullet Seating Micrometer (#RE09085).
• Durable Construction: Heat-treated alloy steel construction built to standard 7/8"-14 die body dimensions, weighing approximately 0.5 to 0.6 kg boxed.

Who is the Redding 204 Ruger Full Length Die Set for?

• High-volume varmint hunters — Requires full-length resizing across standard 7/8"-14 thread single-stage or turret presses to ensure smooth chambering and reliable cycling of .204 Ruger ammunition during high-tempo shooting.
• Pest controllers — Relies on SAAMI-spec case resizing for .204 Ruger rifles using a Redding #10 Shellholder to produce consistent field rounds for targeting foxes, feral cats, wild dogs, and rabbits.

Less suitable for: Target shooters using long-ogive or Very Low Drag (VLD) projectiles without fitting a dedicated VLD seating stem, users loading different cartridges such as the .20 Tactical or .22-calibre cases due to strict .204 Ruger dimensional sizing, or benchrest shooters who require neck-sizing dies or bushing-style competition die sets to work fire-formed brass for a single, tight-tolerance rifle chamber.
